what is the pressure range on the switch?
44578
I was able to set it as low as 25 inches water column (27.72 inches water column equals 1 PSI), and calibrated it to 42 inches water column (about 1.5 PSI) for the application where it was being used. Specs say it can go as high as 5 PSI, though I had no reason to check it at that pressure. From where the adjusting wheel ended up being to provide the 1.5 PSI setting, there was still lots more adjustment available to set it higher.

This switch is adjustable. You can set the cut-in and cut-out pressures separately. It's set at the factory for 40/60, but you can make adjustments internally to lower (and I think higher) pressures, e.g., 30/50. (Note: I haven't done this and I don't work for the company and accept no liability.) The Square D web site is not very helpful, but the web site for Pumptrol (the Square D pressure switch brand) has a lot of info. If you look up the 9013 series of pressure switches, you'll probably find the info you're looking for.

the pressure switch is adjustable, the one I order was preset at 40-60 psi......... 40 being the cut-in and 60 being the cut-out........... look for one with the pressure setting you want; otherwise you will have to read directions and set it either higher or lower yourself.......... not hard to do. hope this helps

Not for sure the amp capacity of the switch or your compressor, otherwise it will work

Minimum about 3psi and max 5 psi. We run ours about 4psi. If you run it on a 220 6psi is the best for a thicker steel than 5/16th inch. I really like mine. You have to play with the pressure a bit but you'll know right away if it isn't working.

I used this pressure switch on an air compressor where the motor drew only 14 amps and I set the switch to cut off at 172PSI. As long as you operate the switch within the current limits and the pressure is also within limits, then there should be no problems as I see it.

It is pre-charged to around 32psi and has a valve on the top side to add more air for setting pressure. I did not have to add any air with my pressure switch set for 50-70

High and low pressure settings come pre set from the factory for a given range such as 20/40 or 40/60. That being said either of these pre set pressures can be adjusted by use of 2 pressure adjustment spring loaded screws. There is a limit to the adjustment so you should purchase a switch that is pre-set closest to the pressures needed or wanted for your system. Remember if your system has a bladder type expansion tank the air pressure will need to be reset in the bladder if you change the low pressure setting on your pressure switch. I hope this is beneficial.

Its set at 3200 psi. You change nozzles to get different types of pressure (fan vs. pin point). Hope this helps.

Agree with Eric. My switch is about 12 ft. away but before I "installed" it, I tested it at various distances.

The pressure gauge on my unit redlines at 144 psi. I doubt very seriously that it will deliver anything close to that.

Answer to both questions is yes. It IS a pre-charged tank , 38psi, 2#below the average cut-in pressure of 40psi, which is correct. it also has a shrader valve used to check/and or add air. Average well switches are set at 40-60psi great tank , you may also want to change out pressure switch as well

I expect it would work at lower pressure. I would not guess at a lower limit but cannot imagin any damage to the unit as a result.

Depends how high. These switches usually maintain a differential of 20 - 30 psi. ie Low cut out 30, High cut out 50psi. I'v had mine set to cut out at 70psi if that's any help. I did reduce it to the 30 -50 range as in the summer here it easy to blow the pvc pipe. I think max for a water heater is 70psi.

Not exactly. A switch is on or off. This is a variable resistor. The resistance changes with pressure sending more or less voltage to the gauge thus showing more or less pressure. (more or less voltage)

The pressure switch has a small Allen screw. I believe this will adjust the pressures for start and stop.

This is precisely the reason I purchased this pressure switch. I had one that was set to 30-50 and I wanted to raise my house pressure to 40-60 and this pressure switch worked just fine. I have a Goulds 5GS07412 at 275 feet below the surface. I think this is a 1/2 hp.
